Application filed November 29, 1915. Ser1a1 No. 63,961.

To all wheat it (121mm g Be it, known that we, WAfrnii E. BRO N and ,Aniim HoL'Ap'Air, eiti'iens of the United States, ,residiag at\l\funcie, in the county of Delaware. and state offlndiana, have invented ca; in, newand seful, Tinprovements in Operating-Tables, of which the fencer" is ae'peifieatiofi; p I

This entijeh relates, as improvements in,a}p,])a1ra'tus.for facilitating surgical operations upon animals. k p

The present invention ,isernbodied in; and consists of the new ceiistru ction, ,eombination and arrangementof parts shown in the annex d shavin s whi h the. d ren parts or the defies are identified by, simil r characters of reference applied thereto in the several views: in which Figure L is a front view, and Fig. 2 is a plan view of our improved operating table. Fig. 3 is a transverse sectional view taken on the line 3-3 in Fig. 1, and Fig. 4: is a transverse sectional view taken on the line 4.4.- in Fig. 1.. i

The flat table top 1 is supported on suitable standards or legs 2, 2, 3 and 3 Arranged in alinement with the leg 2 is an upright guide bar l. Between this guide bar and the inner face of the leg 2, and retained against displacement by side strips 5, is disposed slidingly a vertical arm 6. Carried by this arm 6 is a head block 7 which registers above ahead block 8 secured to the table top. The facing surfaces of these head blocks are hollowed out, in form as shown in Fig. 3. A lever designated as 9 has its rear end supported loosely on a suitable stud or bolt 10 that is secured to the leg 2 A connecting bar 11 has its up.- per end loosely connected to the member 6 and its lower end is in similar manner con nected to the lever 9. Arranged on the side of the leg 2 is a toothed bar or rack; 12. A tooth 9 secured on the side of the lever 9 engages the teeth of the rack. By a coil spring 13 the lever 9 is urged upwardly, the

upright 6 and its head block 7 being supported normally at the raised position shown in Fig. 3. A guide bar 2 serves to prevent transverse displacement of the lever 9 when same is shifted apart from its normal engagement with the rack 12. 15 designates a longitudinal slot, and 16 designates a slot in the table top, arranged in direction diagonal to the tables edge.

A le er 7, similar in. arrangement to the lever 9 hereinbefore referred to, has its rear end loosely connected to theleg 3 and is reat the raised position bya spring 18. A ,footh.j,],7ff carried by the said lever enthe rael r bar 19 that is secured to the tl e leg 3. A guide bar 3" serves to prevent transverse displacementof the lever when same shifted apart from its norma engagement with the rack 19 efi ibl set. 0 m dar b of leather, has its one end passed underneath theroller 21 thatis carried on a loosely connectedarn 22of the l ever1,7, and is fastned to the underside of the tabletop. The uppe i rfilf iee tad of. hestraai p qvid hook 23 that is adapted to be placed in engagement with the eye-block 24. This eye block has a shank 24! that loosely occupies the slot 16 and is arranged in loose engagement with a retaining bar 25 that is secured at position below and in alineinent with the slot 16.

Rising from the table at the location shown in Fig. 2 is a support arm 26. In holes 26 in this support arm are retained loosely the hemp cords 27 having loop ends as shown. 26 and 26 designate fins formed integral with the arm 26. In the V-shaped openings provided by these fins, the cords when drawn therein are held tightly.

Our improved operating table is especially intended for use in the work of castrating pigs. This important operation, otherwise diflicult, and attended by numerous dangers, both to the operator and to the animal, is, by our invention, rendered comparatively simple and easy of accomplishment. The operation is possible of accomplishinent by a single individual,liability of accident is reduced to a minimum, and facility for medical treatment and the application of antiseptics is afforded.

The manner of using the invention is as follows:-The animal is disposed on the table top its head being passed over the block 8. The operator with his foot depresses the lever 9 which lowers the head block 7 until the neck of the animal is held securely. The band 20 is then drawn about the animals body the hook 23 being placed at engagement with the eye block 24:. The operator, with his right foot then lowers the lever 17 which causes the band to tighten against and to hold the body of the animal against movement. It will be understood that bythe operation of the tooth of eaa e of the levers 9 and 17 engaging the respective rack bars 12 and 19, the said levers are retained securely at the lowered positions. By having the elongated slot 15, and the range of adjustment provided for the eye block 24 by the slot 16, it is apparent that the device is capable of being handled to accommodating animals of different sizes. The animal having been secured at place, the next step is to secure its feet against movement. The loops of the cords 24 are fastened to the feet and the free ends of the cord are then drawn taut over the arm 26 and brought into tightened condition at the fins. With the animal thus held at position on the table top the operator is afiorded every facility for performing the operation and for the administration of such treatment as may be necessary.

What We claim as our invention, and desire to secure by Letters Patent, is

1. In an operating table, the combination of means to hold the animals head, an eye block capable of being adjusted to diiferent positions on the table top, a flexible band having its free end adapted to be detachably connected to tlie eye block, and means operable from below the table top to tighten and hold the band.

2. An operating table comprising a pair of head blocks, means operable from underneath the table to move the head blocks to and to hold same at closed position, an eye block capable of being adjusted to different positions on the table top, a flexible band having its free end adapted to be detacl1- ably connected to the eye block, and means operable from below the table top to tighten and hold the said band.

In testimony whereof We afiix our signatures in presence of two Witnesses.
